WEB SPLICING DEVICE Original Filed Aug. 29, 1932 2 Sheets-Sheet 2 Patented Dec. 2 2, 1936 UNITED STATES PATENT OFFICE to Wood Newspaper Machinery Corporation,

New York, N. Y., a corporation of Virginia Application August 29, 1932, Serial No. 630,972 Renewed May 6, 1935 6 Claims.

This invention relates to a device for use in splicing webs to fresh web rolls and it is particularly adapted for that type of web splicing in which the speed of the press is somewhat reduced during the splicing operation, that is, for small plants.

The principal objects of the invention are to provide means whereby the running web can be pressed back against the incoming roll to speed it up by means controlled and operated by hand, thus constituting a simple machine for this purpose; to provide means whereby this can be accomplished between a series of tension members, thereby keeping the tension on the running butt at the time the splicing is done and adding to the eficiency, and to provide for severing the old web by a very simple hand motion which constitutes a continuation of the motion for pressing the web back against the incoming roll. This provides a device which is manually operated by the reel man in a very simple manner and the mechanism is simple and efiicient. It is a device for use in smaller plants where a full automatic machine is not desired.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is an end view of a web splicing machine constructed in accordance with this invention;

Fig. 2 is a side view as indicated by the arrow 2 in Fig. l, and

Figs. 3, 4 and are enlarged views of the web pressing part of the device, shown in three different positions.

The invention is designed to be used with a reel I0 for supporting the running roll or butt II, fresh roll I2 and a spare roll I3 at certain times but it is capable of being used with any kind of a reel or other supporting means, whether supporting one or more rolls at a time. No means has been shown for operating the reel as that can be operated by any well known mechanical driving mechanism or in any other desired way.

The web W of course passes from the running roll II over one or more guide rolls I4 to the press, a part of the frame I5 of which is shown. A series of tension straps I6 is shown, each strap being detachably connected by a hook IT with a link I8, fixed at or near the fioor of the press room. Each strap is connected to the end of a lever I9, these levers being pivoted individually on a shaft 20. Each lever has a removable Weight 2| on the end, which can be adjusted to keep the straps taut. These straps are so located as to put a tension at all times on the stub I i that is being exhausted.

It will be seen that the web W normally is located, just before the splicing operation, in the space between the fresh roll I2 and the straps It. At an elevated point is a shaft 22 on which is pivoted a frame 23 which carries at the bottom a shaft 24. This frame is a single element which can swing about or with its shaft 22 from inoperative position shown in Fig. 3 to the positions shown in Figs. 4 and 5. It is intended to be held in the position shown in Figs. 1 and 3 when it is not in use.

The shaft 2% carries a brush frame 25 provided with a plurality of brushes 2% or other soft surfaced members. These brushes, as indicate-d in Fig. 2, are fixed to this shaft and are spaced so as to allow the straps IE to come between them so that the brushes will not engage these straps. Springs 26 are backed up by brackets on the arms of the frame 23 and normally press the brushes downwardly and forwardly toward the fresh roll. Also fixed on the shaft 2 is a knife frame 21 carrying a series of severing knives 28 which also are made in sections and pass between the straps I6. The springs 28 normally press the knife frame back against a stop 3|.

The operation is very simple. The reel man releases the frame 23 and grasps the handle 29, which is fixed to the frame, swinging the frame forward toward the fresh roll i2. He moves the handle down so that the brushes will come against the web and force it against the roll I2. The springs 2E5 act as a yielding resistance but also keep the knife blades away from the web at first. This forces the running web against the fresh web roll I2 and rotates the roll up to web speed. When the pasted spot 30 on the fresh roll comes around to the right point the paster is made. The operator then forces the handle further inward toward the roll to bring the frame nearer the roll I2. The brushes cannot move further forward but the springs 26 yield and knives 28 move further forward and sever the web, as shown in Fig. 5. The operators hand presses the handle 29 forward all the time. Thereafter the web runs from the fresh web roll and the stub I I is removed.

This is a very simple and effective mechanism for making splices when it is allowable to have the press slowed down during the splicing operation. In that case it partially takes the place of an automatic splicer and can be used in smaller plants because of the reduction in the cost of themachine and cost of maintenance.

It will be noticed that the brushes are pressed against the back of the web to make the front of the web bear against the incoming roll and any desired degree of pressure can be employed. When the brushes are in this position the tension straps are free from the fresh web roll and the contact of the running web itself against the roll can bring the roll up to web speed. On account of the brushes coming between the tension straps sufficient tension can be kept on the running butt at the time the fresh roll is being speeded up and the splice is being made. The operation of severing the web is practically continuous with the speeding up of the roll and pasting it to the web and practically requires no additional time or any additional manipulation.

Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited in this respect otherwise than as set forth in the claims, but what I do claim is:

1. In a web splicing device, the combination with means for supporting a running roll and a fresh roll and tension straps engaging the surface of the running roll, of a movable frame, a series of soft-surfaced members mounted on said frame, means for operating the soft-surfaced members into a position in which they pass between the straps into contact with the web and force the web against the fresh web roll, a series of severing blades in position to move between said straps, said means being mechanically connected with the severing blades and acting to move them into contact with the running web for severing it after the sof -surfaced members have been forced against the web.

2. In a web splicing device, the combination of a swinging frame, a shaft on the frame, a handle on the frame for swinging it manually, a series of brushes fixed on the shaft, and a series of severing knives also fixed to said shaft, said handle, brushes and knives being spaced from each other about the shaft in such positions that when the handle is turned it will first move the brushes into contact with the web and thereafter bring the knives into contact with the web for severing it.

3. In a web splicing device, the combination of a swinging frame, a shaft on the frame, a handle fixed on the frame for swinging it manually, a series of brushes fixed on the shaft, springs for normally moving said brushes in a direction toward the running web to be spliced, anda series of severing knives also fixed to said shaft on the side opposite the brushes, in such position that the handle can be manipulated to move the brushes into contact with the web and thereafter the handle can be moved slightly in the same direction to bring the knives into contact with the web for severing it.

4. In a web splicing device, the combination of a swinging frame, a shaft on the frame, a handle on the frame for swinging it manually, a series of brushes fixed on the shaft, springs for normally moving said brushes in a direction toward the running web to be spliced, a series of. severing knives also fixed to said shaft on the side of the shaft opposite the brushes, and a stop on the frame for limiting the action of the springs.

5. In a web splicing device, the combination of a swinging frame, a shaft on the frame, a handle connected with the frame for swinging it manually, a series of brushes connected with the shaft, and a series of severing knives also connected with said shaft, said handles, brushes and knives being so connected as to move when the shaft moves to bring the brushes into contact with the web and thereafter on a slight further movement of the handle to bring the knives into contact with the web for severing it. 7

6. In a web splicing device, the combination of a swinging frame, a shaft on the frame, a handle on the frame for swinging it manually, a series of brushes fixed on the shaft, and a series of severing manually operated knives also carried by said frame.
